Non-destructive test for mono-block divertor target in JT-60SA

Nakamura, Shigetoshi; Sakurai, Shinji; Ozaki, Hidetsugu; Sakasai, Akira; Seki, Yohji; Yokoyama, Kenji

CFC (Carbon fiber Composite) Mono-block divertor target is required for power handling of 15 MW/m$$^{2}$$ in JT-60SA. Inspection method for screening heat removal capability of mono-block divertor target with infrared thermography is presented. The inspection detects a delay in the surface temperature evolution through an abrupt variation of the water temperature flowing in the cooling tube. Heat removal capability of the mono-block divertor target is evaluated with the delay. Results of heat load test and thermography inspection are considered to assess adequacy for the screening of the thermography inspection with finite element method. Dispersion in density and thermal conductivity of CFC block, coefficient of heat transfer of cooling water in screw-tube, emissivity of CFC, atmospheric temperature, corrected value of infrared thermography camera, and temperature of hot water and cool water cause error in the inspection. The effects of these factors are evaluated.
